I am working on trying to plan out an incubator for when I decide to breed my girls in probably a couple of years or so. Both are still very much babies (the biggest is only about 100g) but I'm already doing research and reading every thread that pops up on this forum. I know that some of the pre-made incubators are basically craptastic and shouldn't be used (likes like the Reptibator and the hova-bator). So my question is this: is it better to buy something like a Accu-Temp 6000 Model, Exo TerraThermoelectric Reptile Egg Incubator, or the large incubator from Nature's Spirit? Or is it better to make your own? If it's better to make your own, how would YOU make it? I've consider buying an old mini-fridge and placing a piece of flexwatt on the door and regulating it with a herpstat. Is that too risky or would it work fine? I also know people who have done something similar with a piece of flexwatt on a foam coolers that you get at walmart. How would you make your incubators? I'd love to have some ideas to pull from when I'm ready to take that step.

Note: When I'm ready for my incubator, I will hopefully have anywhere from 1-6 clutches to incubate. I will be making 2 incubators: one for my 1-3 BP clutches and one for my 1-3 Corn snake clutches.
